WINDOW CHANNEL.

This invention relates to window channels and more particularly to means for attaching 'strips of felt or other cushioningmaterial to the channel bars.

Window channels as commonly7 constructed heretofore have been formed of a channel bar in which is laid a folded strip'of felt orother cushioning material, the arrangement being suchv that the folded strip conforms to the trough shaped construction of the channel and forms a complete lining for the inner walls of the channel bar.

While window channels formed in the manner just described atlord a softguide-way for a window, difficulty is experienced in holding the cushioning material in place since the sliding movement of a window .within its channel bars tends to drag the cushioning material lengthwise of the channel bars.

If an adhesive is used to'secure the cushioning material in the channel bars the adhesive may become soft and sticky upon eX- posure to moisture, and may penetrate through the cushioning material and cause the window to stick to this material. On the other hand, if rivets, nails or other metallic fasteners are inserted through the cushioning material to secure it in the channel bar. the window gla'ssis likely to be injured by the engagement of its edges with these metallic fasteners.

Having the foregoing in mind, the present invention contemplates a window channel in which narrow thick strips of cushioning material are secured to thedilferent walls of the channel bar so that the strips lie in spaced relation to each other and are arranged so that they clear the corners of the glass. This arrangement of `the cushioning strips not only facilitates their attachment to the channel bars, aswill presently appear, but by clearing the corners of the glass the dragging friction between the .cushioning material and the sliding window is materially reduced. Furthermore, the tendency of the corners of the glass to cut the cushioning material is eliminated.

The provision ofk narrow spaced strips of cushioning material in accordance with the present invention has the further advantage in that it results in a substantial saving 1n the amount of material required to line a channel bar.

The various features of the invention and rubber window channel A novel arrangement of parts will be best un-L.

The various types of window channels forming the subject matter of the present invention mav be mounted in a wooden window frame as shown in Fig. 2, or they may be mounted in a metal window framefgs shown in Figs. 3, 4, 5 and 7.

In each of the modifications shown it will be noted that the strips of felt or. other cushioning material -10 are relatively1 narrow so that when secured in place they lie in spaced relation to each other, and are positioned to engage the opposite side faces of thewindow glass 11, but do not engage the glass at the corners formed at the juncture of the side walls and edge of the glass.

In each of the constructions shown thev I as it increases the cushioning effect of vthe window supporting channel. In'Figs. 1 to 7 I inclusive the' channelbar is shown as formed of sheet metal, whereas in Figs. 8 and 9`the channel bar is formed of rubber.

In the embodiment of the invention shown in Figs. 1 to 5 inclusive, the cushioning strips 10 are secured tothe side walls 12 of the chan- .nel bar near the outer edge of these walls by bending the metal of each side wall to form a strip receiving groove or trough, and the metal ofthe bottom wall 13 of the channel lbar is likewise bent to form a strip holding groove.

In Figs. 1 andv 2, the strip receiving-channels for the side walls are'formed by bending inwardly the marginal edge'of the' 4side walls as at 14 and by cutting the metal of the side walls along three sides of the openings 15 to lform the li s 16 which are bent inwardly to form one side of the strip receiving groove above mentioned. lThe cushioning strips 10 are made relatively thick and narrow as shown and are retained in place by bending .1. the portions 14 and 16 into gripping engage-'- vment with the strip. The construction is s uch" 25 `wardly a substantial distance beyond the that the material of each strip extends ingroove forming portions 14 and 16 with the result that the strip holding portions 14 and v 16 are prevented,

f viding the holding lips 16.

y 1 nosphere cannot enter through these open-l lngs. This is readily done by employing the constructionof Fig. 2 wherein it will be seen that the opening 15 lies under the strip 10 and notA at one side of this strip, as in Figs. land 2.;

Various means may be provided for secui-,

ing the windowl channels in -the window frame, and in the construction shown in Figs. 1 and 2 this .is accomplished in accordance with the present inventionby providing vthe channelbar withthe additional lips 17 which are bent Vso that they extend outwardly be yond theside walls 12, the construction being such that as the window channel of Figs. 1

and 2 is forced lengthwise df the wooden win- -.dow frame 18 the lip's 17 will cut a groove lengthwise of the wooden frame in which the li s 17, lie to hold the window channel in p ace, or these lips 17 may project from the side walls 12 into slots prevlously formed in the window frame 18. 'l i The resilient walls-12 are so constructed that .they normally extend inwardly toward eachother as shown in Fig.' 1, with the result that when the parts are assembled as in Fig. 2 .each' side Wall 12 is free to yield outwardly slightly under pressure .toward the wall of the window frame-18.. In this mannerthe cushioning effect adorded the glass by the strips 10 is increased by the resiliency of the side walls 12.

In Figs: 3, 4, 5 and 7 the hanilei bar is shown as mounted within a metal window frame 19. Various means might be employed for securing thechannel bar within this metal frame, and in the construction shown in Figs.. 3 and 5 this is accomplished by spot welding, as indicated by 20. v'

In the constructions shown in Figs. 3, 4 and 5 the strip holding lips 16 of Figs. 1 and 2 are not employed, but the sheet metal forming the channel bar is bent to form` the various strip receiving grooves, as clearly shown by the drawings. In the construction shown in Fig. 3 only thecentral portion ofthe bottom wall engages the base portion of the wins dow lframe 19, and the side walls 12 have a tendency to spring inwardlv'away from the side walls of the window vframe, as shown, but the introduction of the window 11 between the cushioning strips will force these side walls outwardly intov engagement with the side walls of the window frame 19. In the embodiment f the inyention shown in Fig. 4 the constructionis'such that .the strip engaging portion of the bottom wall 13 normally hes in spaced relation to the bottom. 'of the window vframe 19, vas shown.

This constructionhas the advantage thatfthe base portion 'of the channel bar may lyield outwardly under pressure towards the window frame, thus increasing the cushioning effect afforded the edge of the glass 11. The construction of Fig. 4 has a further advantage in that it is frictionally held in the window Vframe' 19 by the outward pressure of the rounded port-ions 20 of the channel bar, als...

will be apparent from the drawing.

In Fig. 5 the groove which retains the bottom strip 10 in place is formed'by bending the metal of the channel bar. back upon itself,

as indicated at 2l, and one side of each of the;`

grooves provided in the side ilarly formed.

The strips employed inlining windowchannels Vare usually formed of felt, but it weather, due tothe swelling of the felt channel lining.

This diiiiculty is corrected in accordance with the present invention by arranging the felt strips 10 so that the libres of t-hese strips extend at right angles to the face of thewalls`12 is simi vis found that'these felt strips expand to a glass they engage, as shown in Figs. 1 to 5 ,y incluslve, instead of extending parallel to the f face of the glass as has been customary heretofore.

In other words, it" has been customary heretofore to lay a felt stripI in the window channel so that a. at face of the felt strip engages a face of ,the window. But in accordance with the present invention the relatively narrowA thick strips 1() are arranged .in the channel supporting grooves so that an edge ofeach strip, rather than a lflat face thereof, rests against the glass 11.l As a result of this construct-ion, when a strip 10 expands, due to the presence of moisture, the expansion takes place'in a direction parallel to the face of the glass which the strip engages, rather than toward the glass as has been customary heretofore. c'lfhe 'expansion of the strips 10 just mentioned will not in 'may bulge outwardly somewhat between the spaced lips 16.

It will be seen from the foregoing that by arranging thel strips 10 Iso that the fibres ex'- tend at right angles to the face of the glass 10, as indicated in the drawings, the bind-I ing effect of the stripsexperienced heretofore in wet weather is entirely eliminated, and the present arrangement of the felt strips has the further advantage in that by arranging these strips so that the fibres extend approximately parallel to the side walls 14 and 16 of the strip holdin channels the strips may be more firmly hel in place.

In the constructlon shown Figs. (i and ation. To this endthe walls of the--c anne]` bar are provided with the spacedlholes` 22 adapted'to receive the, binding threads` 23 which pass through the strip `10 and throu h the holes22, as will be apparent from e drawing.

In the embodiment of the invention shown in Fig; 8.thechannel bar is formed of rubber and the side walls 24A andbottom wall 25 of this rubber channel are preferably provided with the felt strips 26` which are fitted in the strip receiving grooyes formed in the inner faces of the walls 24 and 25. These strips may be -fastened in their grooves by the use of cement. The channel bar ofFig. 9, like that of Fig. 8, is made of rubber, but in Fig. 9 the strips 27 are formed ofa fabric material s'uch as a woven product. i

From the foregoing description when read in connection with. the drawings, it will be seen that various means may be employed for attaching the narrow thick cushioning strips -10 to the walls of the channelbar, and that by ymounting the strips :in-spaced relation to ftivey side wa each other, as shown, sof that they do not engage the corners of the glass, the tendency of these corners to cut the cushioning material is avoided. In this manner the friction between the sliding window 11 and strips l0 is reduced and the tendency 0f the sliding window to drag the strips lengthwise of their channel bars is likewise reduced.,
